Caption: For the first time, Chandra has resolved the complex structures at the center of our Milky Way galaxy through X-ray observations. In addition to the supermassive black hole, Sgr A*, astronomers have found the remains of a supernova that exploded some 10,000 years ago. The proximity of the supernova known as Sgr A East to the black hole in the galactic center suggests that the explosion may have prevented material from falling into the black hole, thus "starving" the supermassive black hole for a period of time. By studying the association between Sgr A East and Sgr A*, astronomers hope to learn if this is an example of a common relationship between supernovas and black holes throughout the universe.
